"Estrogens (AmE), oestrogens (BE), or œstrogens, are a group of compounds named for their importance in the estrous cycle of humans and other animals. They are the primary female sex hormones. Natural estrogens are steroid hormones, while some synthetic ones are non-steroidal. Their name comes from the Greek words estrus/οίστρος = sexual desire + gen/γόνο = to generate."
"Estrogens are synthesized in all vertebrates[1] as well as some insects.[2] Their presence in both vertebrates and insects suggests that estrogenic sex hormones have an ancient evolutionary history."
"Estrogens are used as part of some oral contraceptives, in estrogen replacement therapy for postmenopausal women, and in hormone replacement therapy for trans women."
